I don't see anywhere to change the map resolution

The front page says "The following values are configurable: Canvas resolution"
but the config doesn't have that as a setting

Please let me know how to change it

This is not an appropriate location to seek help for ArtMap - the dev is no longer active. Current devs can be found here: https://gitlab.com/BlockStack/ArtMap/issues

--> I believe Fupery failed to update his decision on this wiki prior to quitting development. There is no way to change the Canvas resolution size.
